This reverts commit 0febe11dc5, reversing
changes made to e45d73d7a3.
This has been reverted for caushing Apache to max out threads when running
under mod_wsgi.
1. Specified `resource_prefix` and `resource_url` context more tightly (could be global context)
2. Changed `this.href` to `jQuery(this).prop('href')` as it will never throw a syntax error when upon the condition of a `a.resource-url-analytics` not having a `href` attribute
3. Also added check so that if no `href` is present it doesn't send a blank link to google analytics
